Core Advantages
1. Inherent Permanent Flame Retardancy
Achieved through molecular thermal stabilization during production, not surface coating. LOI reaches above 45% with permanent performance that never decays after washing, baking, or long-term use.
2. Zero Molten Drip & Ultra-Low Smoke
Eliminates secondary scald risk and protects personal safety with minimal smoke density and virtually no toxic gas release during combustion.
3. Excellent High Temperature Resistance
Stable performance at 200-300°C continuous use, withstands 400°C+ short-term exposure while maintaining fiber flexibility and structural strength.
4. Optimal Processing Compatibility
1.5D fine denier with 51mm standard length ensures compatibility with ring spinning, needle-punched nonwoven, and felt production lines worldwide.
5. Superior Chemical & Electrical Performance
Excellent resistance to acids, alkalis, chemical solvents, and radiation with outstanding electrical insulation properties for demanding applications.
Frequently Asked Questions
Q1: Is the flame retardant effect permanent? Will it fail after washing or heating?
A1: The flame retardancy is inherent to the molecular structure formed by thermal oxidation, not a surface coating. The fireproof performance is permanently stable and will not decay after repeated washing, high temperature baking, or long-term use.
Q2: Will molten drip be produced when burning? Is there toxic smoke?
A2: The fiber only carbonizes when burning - no melting, no dripping, no shrinkage. It self-extinguishes away from flame with ultra-low smoke density and almost no toxic gas release, effectively avoiding secondary injury.
Q3: What is the long-term service temperature of this fiber?
A3: It can be used continuously at 200-300°C and can withstand instantaneous high temperature above 400°C while maintaining good flexibility and structural strength without deformation.
Q4: Is 51mm length compatible with needle punching and spinning machines?
A4: 51mm is the standard length for industrial nonwoven and spinning processing. It is fully compatible with needle-punched felt, ring spinning and other equipment, featuring neat cuts, low fly waste and stable processing.
Q5: What is the difference between pre-oxidized fiber and aramid fiber?
A5: Pre-oxidized fiber has higher LOI, no molten drip and lower cost, but slightly lower strength. Aramid has higher strength but may produce molten drip at ultra-high temperatures. Pre-oxidized fiber offers better cost-effectiveness for fireproof and heat insulation applications.
